Designing Sustainable Porous Pavements for Northern Communities
Principal Investigator: Dr. Mandar Dewoolkar (College of Engineering and Mathematical Sciences)
Co-Investigator: Dr. George Pinder (College of Engineering and Mathematical Sciences)
Funding Agencies: VTrans and US DOT
Stormwater runoff from traditional, non-porous pavement systems--including parking lots significantly pollutes our rivers, lakes, and estuaries. Alternative porous pavement systems allow polluted water to pass through into the natural sub-base thereby reducing the quantity of stormwater and potentially improving water quality. This UVM research project is characterizing the suitability of porous concrete pavements for northern communities. Research focuses on an instrumented park and ride facility built by VTrans in Randolph, Vermont.
In addition to the basic mix design, of particular interest are the effects of factors such as freeze-thaw, wear and tear, and winter maintenance on the system properties. These determinations can then lead to development of more appropriate mix design specifications for our region. A numerical model for the overall system (pavement, sub-grade and sub-base) will be developed and will allow results to be transferred to other locations.
